AI Floor Plan Drafting for Construction Documents

A construction document floor plan carries more than walls: every partition needs a type tag, every door a number, every room a name and number that match the schedules, and the dimension strings have to close back to the column grid. Nomic drafts the A-101 series in CAD from your design markups or an approved test fit, then checks the sheet against the code and your own schedules before the project architect reviews it.

On the sheet

Floor Plan, annotated

An architectural floor plan with walls, doors, room tags, and the column grid every other discipline draws on.

  1. 1Exterior wall with window openings
  2. 2Door, swing, and door tag
  3. 3Room name and number
  4. 4Partition type tag

The problem

Every design change touches four things on the floor plan

When the design team moves a wall in a test fit, the floor plan needs more than a moved line. The partition tag changes if the wall now separates a corridor, the door in it gets renumbered, the room behind it changes area and maybe name, and two dimension strings no longer add up to the grid. On a 40,000 square foot floor, a round of design markups can mean a day of that bookkeeping before anyone looks at the design again.

The errors that come back from plan check and from the contractor are rarely design errors. They are a door tag that points at a number missing from the door schedule, a 1-hour corridor wall tagged as a non-rated partition, a dimension taken to face of finish on one string and face of stud on the next, and a room number that reads 214 on the plan and 241 on the finish schedule.

01 / Inputs

Start from the markups or the test fit

Attach the design markups, the approved test fit, and the current background, and say which floors to draft. Nomic reads hand sketches over printed plans and Bluebeam markups, the structural column grid, and your partition type sheet, so every wall it draws starts with a type assigned.

  • Test fits and space plans turned into CD-level floor plans
  • Scanned hand markups and PDF markups read for wall and door moves
  • Column grid and core walls taken from the structural and base building DWGs
02 / Drafting

Walls, doors, rooms, and dimensions on one sheet

Nomic draws each partition on the layer for its type, tags it, places door tags numbered from the room they serve, and dimensions the walls to the column grid using your firm's convention for face of stud or centerline. Room tags carry the name, number, and area, and keynotes go in with the legend.

  • Wall type tags at every partition change, rated walls on their own layer
  • Door numbers derived from room numbers, such as 214A and 214B
  • Dimension strings closed to the grid, checked so the segments add up
03 / Check

Checked against the code and your own schedules

Before the sheet goes to the project architect, Nomic checks door clear widths, maneuvering clearances, and corridor widths against the code edition you name, and compares tags on the plan with the door and finish schedules. Everything it drew is clouded, and the questions it could not settle are listed.

  • Door clear widths and latch-side clearances checked at every door
  • Plan tags compared with the door schedule and finish schedule
  • Walls that miss the grid or a shaft flagged for the architect

Checked against

The code and documents behind every sheet

Name the editions the project is designed to and Nomic checks its own drawing against them before handing it back. Your engineer or architect of record makes the final call and stamps the set.

  • IBC Chapter 10 means of egress
  • IBC Chapter 7 rated wall assemblies
  • 2010 ADA Standards for Accessible Design
  • ICC A117.1
  • Your door, finish, and partition type schedules
  • Your firm CAD standards

How it works

From a sentence to a stamped set

  1. Step 1

    Ask for the drawing

    Say what the sheet needs to show and attach the backgrounds, markups, cutsheets, or photos. A sentence is enough to start.

  2. Step 2

    Nomic drafts it in CAD

    Nomic works in CAD on its own computer, on your layers and blocks, following how your firm drew the same thing before. It saves real DWG files to the project.

  3. Step 3

    Nomic checks its own work

    The drawing is checked against the code editions you name and the source documents. Everything Nomic drew is clouded, and open questions are listed.

  4. Step 4

    Your team reviews and stamps

    Your engineers and architects review the clouded changes, make the final call, and issue the set under their own stamp.

FAQ

Frequently asked questions

Yes. Nomic works in CAD on its own computer and saves floor plans as DWG files with partitions on your layers, wall type tags, door tags, room names and numbers, dimensions, and keynotes. The project architect reviews the sheet, and the architect of record stamps it.

Yes. Attach the approved test fit and the base building background, and Nomic redraws the layout as a CD floor plan: walls assigned to partition types, doors numbered, rooms tagged, and dimensions tied to the column grid. Anything the test fit leaves open, such as a wall type at a demising line, goes on the open questions list.

Nomic compares the tags it placed on the plan against the door schedule and finish schedule and flags any number that appears in one place and not the other. It can also hand back a room list and door list in Excel so the schedules start from the plan.

No. Nomic is not a plugin. It drafts on its own computer and saves DWG files you open in AutoCAD or any DWG editor. Teams that document in Revit get DWGs and a change list a modeler can link into the model.

Your architects do. Nomic drafts from the partition types and design you give it and checks the result against the code, but the final call on wall ratings, corridor layout, and code interpretation stays with the architect of record.
